Notes:

1. C2 = 10 mF with CS8441 application.

2. The product of C4 and RT have a direct effect on gain and therefore directly affect temperature compensation.

3. C4 Range; 20 pF to 0.2 mF.

4. R4 Range; 100 kW to 500 kW.

5. The IC must be protected from transients above 60 V and reverse battery conditions.

6. Additional filtering on the FREQIN lead may be required.

7. Gauge coil connections to the IC must be kept as short as possible (≤ 3.0 inch) for best pointer stability.
